WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No.393,676, dated November 27, 1888.

Application filed May 31, 1887. Serial No. 239,762. (No model.)

To aZZ whom it may concern.-

Be it known that 1, PETER WHITE, of St. Louis, Missouri, have made a new and useful Improvement in Water-Closets, of which the following is a full, clear, and exact description.

In water-closets in which the contents of the bowl are removed therefrom by siphonic action this difficulty is experienced. The contents are liable to be drawn upward into the air-pipe used in producing the vacuum, and as the air-pipe usually connects with the bowl-flushing pipe the deposit withdrawn from the water-closet bowl may, via the airexhausting pipe and the bowl-flushing pipe, in part be returned to the bowl again. To prevent this, and to insure a proper discharge of the closet, is the object of this improvement, which consists in employing a defiector between the outlet from the bowl-trap and the inlet into the air-exhausting pipe so constructed and arranged as to permit of the producing of the needed vacuum, but so as to deflectthebowl-contentsasthey risefromthe bowl downward into the dischargepassage, substantially as shown in the annexed drawings,making part of this specification and exhibiting the most desirable mode of carrying out the improvement, in which Figure l is a vertical section on the line 1 1 of Fig. 2, which is a plan of the improved water-closet bowl. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1.

The same letters of reference denote the same parts.

The bowl A is of a familiar type of construct-ion, modified only by the introduction of the improvement under consideration.

The broken line B indicates the normal level at which the liquid contents of the bowl stand. Y

0 represents the passage leading upward from the bowl, and with the bowl forming the customary upper trap.

D represents the air-space above the outlet from the trap, and E is the passage through which the bowl-contents, after passing the trap, are discharged, all of the customary form.

Frcpresents the pipe through which the air is exhausted (by any suitable means, not shown) from the space D,and the bowl thereby emptied.

G represents the deflector used to carry out the improvement. It is in effect-a perforated partition serving to divide the air-space D into a lower, (1, and an upper, (1, space. The perforations in the deflector are for the escape of the air upward from the space (1 into the space d.

To darry out the improvement provision must be made for lifting the contents of the passage 0, and also for moving them side wise to be in position to fall into the passage E. To this end a suction force from two different quarters must act upon the contents from a point overhead, or substantially overhead, and from a point beyond the firstnamed point. Accordingly, the partition G is perforated at two difi'erent points, at g and also at g. The perforation at g is preferably in the form of a number of small perforationssay one-fourth of an inch in diameter-and grouped as shown, and the perforation is preferably a single onesay two inches in diameter. The perforations at g are located, as shown, directly over the passage 0, and the perforation g is located as far as is practicable toward the farther end of the partition. Now when the air is exhausted upward in the air-exhausting pipe F an airdraft sets from the space (I in two directionsupward through the perforations g and thence through the space d to the inlet f of the pipe F, and sidewise through the space (i beneath the partition to the perforation g, and thence through the perforation g to the inlet f. The consequence is the contents of the passage G are lifted above the partition which separates the passage 0 from the downward passage beyond, and are also drawn sidewise, and the resultant movement effects the dis charge of the bowl-contents without drawing any portion thereof into the inlet f. After the movement is well started there is apt to be a downward current setting through the perforations g, as indicated by the arrow as. The movement of the bowl-contents is mainly as indicated b the arrow 00. The movement of the air is indicated generally by the arrow :0

I claim I A Water-closet bowl having a partition separating the space D into the spaces (1 and d, in combination with the air-exhausting pipe, said partition being perforated at two points,

at a point substantially above the passage 0, and also at a point at or toward the farther to end of the partition, substantially as and for the purpose described.
